Batteries 1350 can be seen located within the housing cavity 1303 as part of the sensing assembly 1300. A first portion 1226 of the lower stem 1225 can be substantially hollow as previously described; a second portion 1228 or transition portion can be coupled to the first portion 1226 and can serve as a transition in connection from the substantially hollow lower stem 1225 to the valve reinforcement 1280. The second portion 1228 can define an antenna channel 1229 extending from a lower end of the second portion 1228 to an upper end of the second portion 1228. The antenna channel 1229 can allow wired electronics to communicate from the portions of the sensing assembly 1300 within the housing cavity 1303 to an antenna 1370 by a wire 1371. A sheath 1372 can be included in various aspects.

As seen with reference to FIG. 4, the channel 1314 can be defined within the sensor housing 1301. A nozzle 1490 can be located within or otherwise in fluid communication with the channel 1314. The nozzle 1490 can provide a location of attachment for a sensor 1420. The nozzle 1490 can be defined within or placed within the channel 1314 in various aspects.

The sensor 1420 can be of a variety of sensors known in the art, including pressure, temperature, salinity, purity, and various other sensing types. The PCB 1410 can also be in electrical communication with the batteries 1350. Additionally, a channel 1491 can be defined within the nozzle 1490 to provide fluid communication through the nozzle 1490.

A battery container 1360 can be a semi-rigid container to hold batteries 1350 without substantial bulk. The battery container 1360 can be arranged to be placed around and to contain the batteries 1350. As a result, the battery container 1360 can serve as a rigid or semi-rigid container in various aspects for a plurality of batteries 1350. In the current aspect, the battery container 1360 can contain six or seven batteries 1350. The battery container 1360 can be a part of the sensing assembly 1300. A mounting bracket 1362 can be included to locate and to contain portions of the sensing assembly 1300 within the housing cavity 1303. As can be seen, nut threading 1308 can be seen formed on an outer surface of the sensor housing 1301. Additionally, mounting threading 1309 can be seen formed on an outer surface of the sensor housing 1301.

As seen with reference to FIGS. 6-7, the valve reinforcement 1280 can comprise at least one stanchion 1286. The valve reinforcement 1280 can define the stem bore 1284 that can be in communication with the electronics cavity 1287. As can be seen, the electronics cavity 1287 can be enlarged as compared to the stem bore 1284 such that a diameter of the electronics cavity 1287 can be larger than a diameter of the stem bore 1284. The enlarged diameter can allow the location of the electronics of the sensing assembly 1300 within the sensor housing 1301 (seen with reference to FIG. 5) to be mounted within the electronics cavity 1287. As such, the electronics cavity 1287 can comprise threading 1288 formed by a surface of the electronics cavity 1287 to interact with the mounting threading 1309 of the sensor housing 1301. Such threading can help define a fluid seal and a strong connection when the sensor housing 1301 is attached to the valve reinforcement 1280. With much of the electronics of the sensing assembly 1300 located with the lower stem 1225, a connection of the electronics within the electronics cavity 1287 can communicate upwards through the lower stem 1225 as previously indicated.

As seen with reference to FIG. 8, the stem bore 1254 of the valve plate 1250 can be enlarged to accommodate location of the sensor housing 1301 within the valve assembly 1220.

The valve nut 1270 can be seen with reference to FIGS. 9A-9B. As can be seen, the valve nut 1270 can comprise threading 1271 defined within a nut cavity 1272. The threading 1271 can interact with the nut thread 1308 of the sensor housing 1301 to provide a secure attachment of the valve retainer 1260. In the current aspect, the valve nut 1270 can define a fluid channel 1274 providing a fluid pathway from the nut cavity 1272 to an exterior of the valve nut 1270. In use, the valve nut 1270 can be located within the shoe 1030 such that it is in direct interaction with fluid flowing within the shoe 1030. Therefore, the fluid pathway provided by the valve nut 1270 can allow flow of fluid into the nut cavity 1272 and thereby into the sensor housing 1301 to be sensed be the sensor 1420.

As seen with returning reference to FIG. 2-3, a sealing cap 1530 can be arranged to seal a top end of the lower stem 1225 and provide a fluid seal to prevent fluid within the fire hydrant 1000 from coming into contact with any electronics. The sealing cap 1530 can be formed of a fluid sealing material such as rubber or the like. The sealing cap 1530 can define a void to allow portions of the antenna 1370 to protrude through. In various aspects, the sealing cap 1530 can be of a molded material, and portions of the sealing cap 1530 can be molded around the antenna 1370. The antenna 1370 can be allowed to protrude through to allow near-field communication with a repeater elsewhere in the fire hydrant 1000 or in close proximity to the fire hydrant 1000 such that interference is minimized. In one aspect, the antenna 1370 can be in wireless communication with a repeater located within the bonnet 1130. The repeater can then communicate data from the antenna 1370 to a network outside of the fire hydrant 1000. In various aspects, the bonnet 1130 can be formed of a non-ferrous material to prevent communication interference from the bonnet 1130 to the network. The sealing cap 1530 can be attached to the lower stem 1225 by rivets (not shown). The sealing cap 1530 can also comprise a post 1531 for coupling the upper stem 1222 to the lower stem 1225. As such, in various aspects, the sealing cap 1530 can serve as a coupling. In the current aspect, the post 1531 can define a coupling port 1533 into which a rivet or fastener can be located to couple the upper stem 1222 to the lower stem 1225. In various aspects, an upper stem coupling 1536 can be utilized as a portion of the upper stem 1222 to connect the sealing cap 1530 to the upper stem 1222. In various aspects, the sealing cap 1530 can be attached by various means, including threading, gluing, sealing, or integrated formation.

Another aspect of a fire hydrant 2000 can be seen with respect to FIG. 10-11. The fire hydrant 2000 can comprise a valve assembly 2220 and the lower barrel 1230, as well as many other portions similar to the fire hydrant 1000. In the current aspect, the fire hydrant 2000 can comprise a sensing assembly 2300. Batteries 1350 can be located within the lower stem 1225 in a battery container (not shown in detail) that aligns the batteries 1350 in a vertical arrangement rather than in a side-by-side arrangement. As such, portions of the sensing assembly 2300 can be in varied arrangement. As contrasted with fire hydrant 1000, fire hydrant 2000 can omit certain features such as the sensor housing 1301. By omitting the sensor housing 1301, the fire hydrant 2000 can be arranged with parts that do not include enlarged openings. For example, the valve plate 2250 of the current aspect can define a stem bore 2254 that is of about the same diameter as the lower stem 1225. Further, a valve reinforcement 2280 need not include any enlarged opening or internal threading to interact with the sensor housing 1301 when the sensor housing 1301 is omitted. In various aspects, the sensor housing 1301 can be included with an arrangement such as fire hydrant 2000.

As seen with reference to FIG. 11, the lower stem 1225 can comprise a transition portion 2228 that is longer than the second portion 1228 of fire hydrant 1000. The transition portion 2228 can define an antenna channel 2229. A valve retainer 2260 can be included in the valve assembly 2220. The valve retainer 2260 can define a channel 2264 in fluid communication with a channel 2255 defined within the valve plate 2250. A vein 3300 can be located within the channels 2264, 2255 such that the vein 3300 is in fluid communication with the region outside of the valve reinforcement 2280 and, therefore, in fluid communication with the fluid inside the shoe 1030.

The valve plate 2250 can further define a sensor recess 2256 for location of various electronic components of the sensing assembly 2300. Similarly, the valve reinforcement 2280 can define a sensor recess 2286 arranged to align with the sensor recess 2256. The sensor 1420 can be located within the sensor recess 2256 such that it is in fluid communication with a channel 3303 defined within the vein 3300 thereby allowing the sensor 1420 to sense various aspects of the fluid within the channel 3303. The PCB 1410 can be located proximate to the sensor 1420 and in electrical communication with the sensor 1420 such that at least a portion of one of the sensor 1420 and the PCB 1410 can be located within at least one of the sensor recess 2286 and the sensor recess 2256. An antenna inlet 2241 can allow a pathway for a wire 1371 to the antenna 1370.
